From the ronalrneiion thus 1": r loe0rilnil ii will he apparent to one skilled in i'he art. that iii, spring 123, aol'. on the collar 8 'ili (l normally i0 niove the bobbin (lriv 12A member into driving engagepulley and hence ,arl its roi'aliv; more oil JO SCCHTD-Qi between the -i the opyos clutch nn having an arm 25 provided with a linger Q6 normally maintained a distance above the axis of the bobbin barrel, when in driv ing connection with the shat't 6, equal to the half diameter of: the wound bobbin. Thus the stop finger 26 will. not engage the waxed thread until the windings on the bobbin have been substantially completed. Secured to the stop-shaft near its opposite end is the driving shaft controlling arm 2?, fig. 2, which is relatively so positioned on the stopshaft with respect to the arm 25 carrying the stoofingcr, that when the latter is in its normal position to be engaged by the thread on a lilledbobbin. the end of the arm .37 is to one side, of the driving shaft axis: and when the? Limp-finger is moved away from the bobbin the, end of the controlling 1 arm 27 will be moved toward the axis oi said driving shaft.

Mounted on the end of the driving shaft controlling arm 27, Fig. 1, is a cam surface 28, which as the arm 2'! is raised or moved toward the axis of the driving shaft, en

gages the rounded end 25) ot the stop head 10, and moves the driving shalt endwise against the tension of the spring 12, thereby disenga ing the bobbin driving clutch-member 18 from the driving pulley 3.

rv'hen the windings on the bobbin have reached the required diameter, it is desirable that the stopping action of the parts shall be quick and etlective to relieve, as far as possible, all injury to the waxed thread by prolonged engagement therewith ot the stop finger, and to avoid (-letectivc winding, as

will be understood by those skilled in the art. Mounted upon the arm 27 is an actuator pin 30 which, when the arm 27 is in its lowest position, defined by a stop 34-, and the stopfingcr is in its position to engage a tilled bobbin, rests against the edge of an actuator, said actuator in the form oi invention shown comprising an arm 31, pivotally mounted at 32 and having anupper portion provided with an incline 3 A spring 35, acting on the arm Bl, tends to i'nove said arm 31 to the right, Fig. 2.

be obvious that when the driving shaft, controlling arm 27 is in its lowest position rest- 1 ing against the stop 34, the actuator pin 30 will n'iaintaln the actuator 31 in the position shown by full lines, Fig, 2: but when the stop finger 2b is met by the thread winding on the bobbin, it will turn the stop-shaft 24- 'and move the controlling arm 27 to carry the actuator pin 30 above the shoulder 36 on the arm 31, whereupon the arm 31, under the impulse of spring 235. will move quickly to the right into dotted line position cans ing tbc incline E3 1 remove the actuator pin 30 and the arm Lildipivard and,consequcntly, the slim-linger 2t. away from the wound bobbin.

in order that the stop-linger 26 may From this ctmstruction it will readily impart to the Controlling arm 27 its initial movement toyzair vthe actuator pin 30 above the shoulder 36 ot' the actuator 31, the surface 37 of the actuator. which is engaged by the pin 30 during the winding operation, is made somewhat inclined or preferably atv 1 l' i 1 right angles to the tlIUS ot inc arm 27 when the parts are in the position shownby full lines, Fig. i I

Projecting laterally from the end of the controlling arm 27 is a stop-flange 38, which, a lter the cam surface 28 has moved the driying shaft to disengage the bobbin driving clutch member 18 from the, driving pulley 3, comes in contact with a fiat tare ot the stophcud 10. thereby bringing the driving shaft and vouut bobbin to rest. Should a flat face of the stop-head 10 be not in parallelism with the surface of the stop flange 38, as the ram 28 moves the driving shaft to disengage the clutch member and pulley, the yielding nature of the actuator 23. will permit sutlicient delayed action in the rise of the arm 2'? to bring the flange 38 and a flat tace n the stop-head into proper engaging position during the rotation of the stophead without injury to the parts. A pin 42 on the arm 27 contacting with the stophead prevents the arm 27 moving so far up as to disengage the stop-head from the "am and tiangc.

As well known by those familiar with sewing machines usirtg waxed thread, it is essential that the thread be maintained at a suft'cicntlyhigh temperature, whether a shuttle or ncedh v thread, that. the requisite pliability be secured for prope action. lleretofore, in winding bobbins with waxed thread l'or use in such machines, a number or bobbins have been wound and when wanted for use have been properly heated by baking or otherwise, a system both objectionable and expensive, because it requires a large number of bobbins, and when heated after being wound there is lack of uniformity in the oit'tusion of heat. In the present invention, therctore, the winding devices are preterably supported by a bracket or frame A scoured to or forming part of a wax thread sewing machine, so that the attendant operating the sewing machine may'wind his own bobbins as needed, and since he uses only one bobbin at a time, only two bobbins are required tor any one machine.

The bracket o-r'irame A is preferably made as a hollow casting in part and is heated by steam supplied thereto through a pipe ltl from a suitable source, a pip'efll being provided to secure-drainage or circulation. From the construction described it will be obvious that heat supplied to the bracket orlrame A is transmitted tothe bobbin and its load, so that, in practice, it is only .necessary for the attendant to place an empty the miliev winding 7: i ii:
